Albizia Lebbek

This study was undertaken to evaluate the effect of supplements of siris (Albizia lebbeck) flowers and leaves on Merino wethers fed Mitchell grass hay (Astrebla spp.). Three groups, each of 6 sheep, were fed the following diets: hammermilled Mitchell grass hay ad libitum (M); M + 181 g DM/day of siris flowers (MF), and M + 216 g DM/day of siris leaves (ML). The experiment, conducted over 17 days, measured feed intake and digestibility, nitrogen (N) retention, and plasma glucose and urea concentrations. The total DM intakes by MF and ML sheep were significantly (P<0.01) higher than those in M sheep. As a result of the supplement of siris flowers, the digestibility of the MF diet was highest (P<0.01). Sheep fed the M diet showed negative N retention, while MF and ML sheep showed positive N retention. The increased (P<0.01) N retention in the MF and ML sheep was associated with increased (P<0.01) urinary N excretion. The improved nutritional state of MF and ML sheep was associated with increases in plasma glucose and urea concentrations. Environmental temperature, which reached a mean daily maximum of 31.3�C, did not interact with the dietary treatments.

SUMMARYFive sheep were fitted with rumen cannulas and fed once daily ad libitumat 09.00 h with a low-quality mixed-grass hay or a good-quality lucerne hay. The effects of a second amount of the same hay or of the second hay distributed at the end of the large meal following the morning distribution, when rumen fill reaches its daily maximum, were investigated for feed intake, alimentary behaviour and rumen fill. The second distribution induced a true meal (200–400 g dry matter intake), except in the case of mixed grass offered after lucerne. On the basis of initial eating rate and the amount ingested, the highest palatability was for lucerne offered after mixed grass, and the lowest for mixed grass offered after lucerne. Diet selection was more pronounced with lucerne than with mixed grass, as indicated by the larger decrease in the neutral detergent fibre content of the fraction ingested. The true meals following the second distribution were associated with an increase in rumen fill up to 10% of the daily maximum observed without the second distribution. However, rumen fill with lucerne remained 1 kg lower than with mixed-grass hay, even after a second meal. It is concluded that the sensory response induced by a distribution of a sufficiently palatable hay is able to override the satiety signals due to rumen fill, and that there is a permanent balance between the stimuli related to the characteristics of the food available and those related to reticulo-ruminal digesta.

Environmental Temperatures

A trial designed to investigate the effects of two environmental temperatures, three feeding regimes and the interactions between them is described. A temperature of 72° F. was better than one of 54° F. for bacon pigs between 40 lb. and 200 lb. weight. The higher temperature resulted in faster growth, more efficient feed conversion and increased length of carcass. Other carcass characteristics were not significantly altered. Ad libitum feeding resulted in faster growth and fatter carcasses than restricted feeding, but did not have a significant effect on efficiency of feed conversion. When feed intake was restricted, feeding pigs once daily or twice daily resulted in similar performance and carcass composition.There was a significant interaction between environmental temperature and feeding method for average daily gain in that pigs fed ad libitum grew faster at the low temperature and pigs fed restricted amounts of feed grew faster at the high temperature. No other interaction reached significant levels.

Daily Gain

Thirty-two large-frame crossbred steers (443 ± 5 kg) were used to determine the nutritive value of cracked corn, rolled barley, rolled oats and rolled wheat in finishing diets for beef cattle fed medium-quality grass hay. Diets contained about 54% grains, 40% grass hay and 6% of a supplement of minerals, vitamins and lasalocid. Total daily dry matter (DM) intake ranged from 9.52 to 10.24 kg, average daily gain from 1.09 to 1.17 kg and gain to feed ratio from 0.113 to 0.121, but these values were not statistically different (P > 0.05). Apparent digestibilities of DM and energy of steers receiving the oats diet were lower than those of steers receiving the wheat diet (P < 0.05), the other diets having intermediate values. Apparent digestion coefficient of protein was higher for the oats diet (P < 0.05) than for other diets. Acid detergent fiber digestibility was higher (P < 0.05) and starch digestibility was lower (P < 0.05) in steers receiving corn than in those receiving barley, oats or wheat. The results indicate that nutritive value of all diets was similar. Key words: Grains, fattening steers, digestibility

Cereal grains are often subjected to physical processing before being fed to equids. However, little information is available on how physical processing of cereals affects degradation dynamics in equids. This experiment examines the effect of two physical processing methods (micronisation and extrusion) on in situ degradation of barley in the caecum of poniesThree caecally fistulated mature Welsh-cross pony geldings (approx. LW 270kg) were offered ad libitum grass hay plus minerals. Incubation bags (monofilament polyester 6.5 x 20cm, 41μm pores, 16mg/cm2 sample size) containing either unprocessed barley (UB), micronised barley (MB) or extruded barley (EB) were incubated in the caecum for fixed times according to both a forward (0, 2, 4, 6, 12, 8, 24, 48h) and reverse (48, 24, 8, 4, 12, 6, 2, 0h) incubation sequence. For each feedstuff residues from each time were bulked within pony and across incubation sequence for subsequent analysis of dry matter (DM) and starch (STC). Degradation profiles were fitted to the DM and STC disappearance data according to Ørskov and McDonald (1979).

Three yearling Cheviot × Suffolk ewes and three Columbia wethers were confined in metabolic cages and fed ad libitum fresh and dried marrow-stem kale (Brassica oleracea var. acephala D.C.) harvested in mid- and late October. Chemical analyses of the forages indicated no marked effects on any of the plant constituents due to drying or advancing maturity. Digestibility measurements demonstrated that marrow-stem kale (MSK) was a highly digestible material with an average dry matter digestibility of 78%. The fresh forages had higher (P < 0.05) dry matter and gross energy digestibility values than the dried form. Dry matter digestibility coefficients were higher (P < 0.05) for late October as compared with the earlier harvest. A trend toward higher (P > 0.05) voluntary intake values due to drying maturity was observed with an average relative intake of 80%. The nutritive value index averaged 65, thus indicating a digestible energy intake similar to a high-quality (legume) forage.

De-hydrated forages are often fed to equids in the UK in place of more traditional grass hay, particularly where individual animals are known to have a sensitivity to dusty, mouldy hay which may play a part inducing respiratory problems such as chronic obstructive pulmonary disease (COPD). One such alternative forage is short-chop de-hydrated grass. However, there is very little information available on voluntary feed intake (VFI), apparent digestibility and nutrient intake parameters when de-hydrated grass is offered to equids compared with traditional grass hay. This study examines the VFI and apparent digestibility in vivo of a short-chop de-hydrated grass compared with a traditional grass hay and determines their ability to meet the predicted energy and protein needs of mature ponies.Six mature Welsh-cross pony geldings with a mean liveweight (LW) of 281 kg (s.e.d. 0.89) were individually housed and offered ad libitum access to either short-chop de-hydrated grass (DHG) or traditional grass hay (HAY) plus 60 g/h/d minerals. The DHG and HAY were made from the same 2nd cut perennial ryegrass sward cut on the same day.

The objective of the present experiment was to study the effects of the third-cut grass silage compared with the first- and second-cut silages on intake, performance and carcass characteristics of finishing bulls. A feeding experiment comprised 45 Simmental bulls which were fed a total mixed ration ad libitum. The three dietary treatments included either first-, second- or third-cut grass silage (550 g kg-1 dry matter), rolled barley (435 g kg-1 dry matter) and a mineral-vitamin mixture (15 g kg-1 dry matter). Dry matter and energy intakes and growth rates of the bulls increased when either first- or third-cut silages were used instead of the second-cut silage. This was probably due to differences in digestibility, which was the lowest in the second-cut silage. There were no differences in intake or growth between the first- and third-cut silage-based rations. No significant differences in carcass traits among the feeding treatments were observed.

The experiment which lasted for seventy (70) days was conducted to determine the effects of various dietary levels of sunflower seed meal (SSM) on the performance of growing rabbits. Thirty- two (32) indigenous breeds of rabbits obtained from small-scale producers were used in study. They were individually weighed and randomly assigned to the four (4) dietary treatments, in which 0,10, 20 and 30% of the groundnut cake was replaced by SSM, respectively. The diets contained 2391.76, 2387.44, 2383.12 and 2378.80 Kcal ME/kg for diets 1,2,3 and 4, respectively. The crude protein (CP) was approximately 14.0% for the four (4) experimental diets. The diets, in mash form were fed to the rabbits ad libitum. There was no significant difference (P > 0.05) amongst the treatments in all the parameters examined. However, he incorporation of SSM resulted in a considerable decrease in feed cost with increasing levels of SSM. Thc. results of this Study therefore suggest that 30% or more of the GNC could be replaced by SSM in the diets of growing rabbits without deleterious effect on performance.

Tarramba leucaena (Leucaena leucocephala cv. Tarramba) foliage had per kilogram dry matter, 169 g protein and 29.8 g condensed tannins. Its value as a supplement, given either with or without urea, to sheep given a low-quality Callide Rhodes grass (Chloris gayana cv. Callide) hay was studied. Six rumen fistulated sheep (mean s.d. liveweight, 34 1.4 kg) were used to compare 6 dietary treatments in an incomplete latin square design. Rhodes grass hay was given ad libitum either alone, or with urea 7 g/day (U), or with leucaena 150 g/day (L150), or leucaena with urea (L150U), or leucaena 300 g/day (L300), or leucaena with urea (L300U). Digestible organic matter intake was increased significantly by leucaena supplementation although digestibility of the whole diet did not alter. Rumen fluid ammonia-N was not altered by leucaena supplementation, but was increased by urea. This suggests that Tarramba foliage protein has some resistance to ruminal degradation. Liquid and solids passage rates were not affected by the treatments. Microbial nitrogen supply to the intestine (g/day), and the efficiency of microbial nitrogen synthesis (g/kg organic matter apparently digested in the rumen), were increased by leucaena supplementation (P<0.01). Microbial protein synthesis was the only response in which 300 g/day air-dry Tarramba foliage gave improved results over 150 g/day.
